v1.13.0

• RemoteConversation hooks now work end-to-end with the agent server. hook_config is now forwarded correctly, so remote conversations can execute server-side hooks instead of silently dropping them.
• Agent-server event APIs gained hook observability. Event consumers may now receive HookExecutionEvent objects, and event.source may now be "hook".
• Remote/subagent support expanded. StartConversationRequest now accepts agent_definitions, allowing server-side conversations to see client-registered subagents used by DelegateTool / TaskSetTool.
• SDK usability improved across the release line. Notable additions since v1.12.0 include rerun_actions, configurable marketplace paths, enable/disable support for installed skills/plugins, and new plugin/skill lifecycle examples.
